 I am Shelly Menocha and I am Professor of Learning Technologies and Social Computing in the Faculty of STEM. Our research program has been nominated for the Outstanding Impact of Research on Society and Prosperity. Our research program is on digital health variables and specifically activity monitors. Activity monitors are off-the-shelf devices from Fitbit, Garmin and Samsung that record activity levels, sleep patterns and heart rate. And our aim has been to investigate how these devices can help to support active and healthier lifestyles in later life. These devices are generally designed for younger people. So we wanted to find out what challenges and usability problems older people would face with these technologies, the privacy and the security issues with the data from these devices and the ethical considerations of using this data in medical interventions. Given the UK's aging profile and as a part of the active and healthy aging agenda and digital NHS, there is an increasing focus for people to maintain active and healthier lifestyles in later life to preserve their motor and mobility skills. And there is an increasing emphasis on self-monitoring of health and medical conditions. And our previous research has shown that if people are more physically active and out and about, it helps to address the problem of social isolation and loneliness in later life and in caring responsibilities.
